Hi all;

I plan to build an HF power amplifier, output about 80-100W, not critical.
It might look like as those used in popular Yaesu, Kenwood or Icom end PA
stages, i.e. first stage as driver and the second as final amp., both in
push-pull, transformer-separated. It should run directly with 13.8V supply.
Of course, everything based on popular transistors as MRFxxx, 2SCxxxx,
2SDxxxx, IRFxxx MOS or russian (would be the best, since there are no
problems with buying ones in my country). I've spend several evenings
searching in googles, but I've failed to find anything suitable for me.
Either I'm such a demanding person, or missed something while looking up in
endless vastness of the internet. If anyone knew a well-designed project, or
built one whenever in past, it would be welcome.


Why not just copy a suitable proprietory schematic? What's the problem
with that?
